The Role and Its Impact

Our firmware team develops the embedded firmware that brings Astera Labs' compute connectivity silicon to life, from boot and initialization through link management, telemetry, error handling, and diagnostics. This firmware runs on the embedded processors inside our chips and ships in data centers powering AI infrastructure around the world. Beyond the firmware, the team also develops the COSMOS SDK, the software layer customers and internal teams use to configure, monitor, update, and debug our devices in their systems.

We are looking for an experienced firmware engineer who enjoys working close to the hardware, owns features end to end, and is equally comfortable in a pre-silicon emulation environment and in the lab with real silicon. You understand the whole system, not just the chip: how our devices behave inside customer platforms, and how a customer requirement turns into firmware and SDK. You'll work alongside architects, design and verification engineers, validation teams, and our global firmware teams to take new products from early pre-silicon development through bring-up and into customer deployment.

What You'll Be Doing

• Having fun! by being part of a very strong and cohesive group.

• Design, implement, and maintain real-time embedded firmware in C for high-performance connectivity

• Develop low-level drivers, initialization flows, interrupt handling, and control logic for complex hardware blocks

• Bring up and debug firmware in pre-silicon environments (emulation) ahead of tape-out, and on silicon after it arrives

• Work closely with architecture, design, and verification teams to define HW/FW interfaces and to resolve issues across the hardware/software boundary

• Triage and resolve firmware issues reported by validation, product applications, and customers
